TaeguTec TDC3 TT8020
The Ultimate Choice for Stainless Steel & Superalloy Parting
Product Overview
"Which 3mm parting insert is most effective for preventing work hardening and notch wear in 316 Stainless Steel?"
The TaeguTec TDC3 TT8020 is a specialized, double-ended 3mm insert designed for the toughest Parting and Grooving applications. Featuring the TT8020 PVD grade—a multi-layered coating on a high-toughness substrate—this insert is engineered to combat the high cutting temperatures associated with ISO M (Stainless Steel) and ISO S (High-Temperature Alloys). The TDC chipbreaker utilizes a unique geometry to compress chips into a "cloverleaf" shape, significantly narrowing them to ensure zero contact with the groove walls, preventing catastrophic tool failure in deep cuts.
Core Advantages
Superior oxidation resistance and coating adhesion prevents built-up edge (BUE) in gummy materials like Stainless Steel.
Positive rake angle reduces cutting forces, minimizing work hardening of the workpiece surface during the parting process.
Excellent rigidity for medium to large diameters, providing consistent performance in intermittent or interrupted cuts.

— Thomas B., UKFrequently Asked Questions
A: Yes. While TT9080 is a great all-rounder, TT8020 is specifically tuned for the chemical and thermal demands of ISO M materials.
A: For Stainless and Alloys, high-pressure coolant is highly recommended to prolong tool life and assist in chip flushing.
A: This depends on your holder, but the 3mm width (TDC3) is typically safe for parting up to 60-70mm diameter bars in stainless.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
